25.615 MHz AM 25615 AM - Weak AM voice signal noted

26.745 MHz 26745 kHz - POCSAG pager signals coming in again
26.850 MHz 26850 kHz - Pager signal, mixing in with another data signal
26.865 MHz 26865 kHz - POCSAG pager, possible offset frequency (26.8625 MHz?? 26.863 MHz?)
26.900 MHz 26900 kHz - POCSAG

Absolutely.  26100, 26150, 26200, 26235 (and other offsets like 26237.5, 26238) 26250, 26350, 26400, 26435, 26440, 26450, 26550, 26555 (yes, even though 26.555 LSB is super popular) 26600, 26605, 26610, 26625, 26635, 26645, 26650, 26655, 26695, 26700, 26705, 26745, 26750, 26755, 26845, 26850, 26855, 26865, 26900, 26935 and many others are all known 26 MHz band paging frequencies.  The lower 26 MHz ones are apparently UK hospital pagers and used in other parts of Europe as well.  26600 had a very strong signal on it at points, and was transmitting an unmodulated carrier "idle" when there wasn't data being sent.   

26950 26.950 MHz and 26955 26.955 MHz also apparently heavily used.  There are dozens of others, including in-band frequencies - especially around 27100, 27150, 27300, 27350 and 27360.  Same with 27450, 27500 (and 27505), 27550 and 27650.  Not sure of their origin.  Paging and data links on 26945 and 26960 are apparently out of Russia and likely used elsewhere as well.  There are also pagers operating on 29750, 29800, 29850, 29900, 29950, 30000, 30020 and 30025 all appear to be coming out of Europe.  I know that at one time anyway, 30.020 MHz and 30.025 MHz often had POCSAG signals on them, apparently out of Canada.  Not sure if they're still using those frequencies as well or not.
